Application September 21, lfiififs'erial 1N0. $98-$36 1 Claim.

This invention relates to [storm windows and more particularly to means for mounting storm window assemblies in a window opening. I

The principal object of the invention is the provision of means for mounting a storm win- 'dow assembly in a window opening.

A further object of the invention the provision of a distortable framing member, sections of which may be employed for mounting a storm window assembly in a window opening and the distortion-of 'which in the mounting operation will serve to lock the storm window assembly in a given location in the window opening. e

A still further object of the invention is the provision of a storm window assembly mounting means comprising a rolled new shape of a cross sectional pattern facilitating its 'di'st'oi'tirm upon instanation so that one a ertidnthereer engages a storm window assembly at right angles thereto to effectively locate the same with remtio'n to the window opening in which the installation is made. I r v e The storm window mounting niea'ns shown described herein has beene'esl ned to facilitate the rapid and economical inountiiig' 6f storm wiiidow assemblies and particularly the alumis'tbrr'n window constructions now be ing instanea in ever increasing numb rs. It is wen known that various constructions -havebeen proposed for holding storm window assemblies comprising a master frame and removable glazed or screened inserts thereof and that most of these mounting means heretofore 7' proposed. have necessitated the mounting of the storm window frame directly on M the window opening. practice has two disadvantages in that the average dwelling house window opening is not square and further that very few dwelling house window openings are of the same size. It is therefore a further object of the invention to provide a storm window assembly mounting means which will automatically compensate for differences in widths and heights of the window opening in which the storm window assembly is being installed.

With the foregoing and other objects in view which will appear as the description proceeds,

the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed; it

without departing "from the s'pirit of the invention.

This

2 The invention is illustrated in the accompany ing drawing, wherein Figure -1 is a horizontal cross'section of a per"- tion-ofa dwelling house window opening showing a section of a storm window assembly mounted therein.

Figure 2 is horizontal cross section of a portion of a dwelling house window opening show"- ing a section of a storm window assembly mounted therein by means of a modified mounting member.

Figure-3 is a perspective view of the mounting member shown in Figure 1.

Figure 4 is a perspective view of the mhun'ting member shown in Figure 2.

By referring to the drawings and Figure 1 in particular; it will be seen that a dwelling house window opening is generally indicated by the numeral H3 and that the exterior casing thereof is indicated by the numeral H, and a blind stop is indicated by the numeral !2. As is known, the blind stop I2 and the casing l l are positioned on a vertical plane on each side of the window opening. It is also known that it is common practice to mount astorm window construction in the area adjacent the exterior casing II and in front of the blind stop I2 to the end that the exterior of the storm window so mounted lies flush with the plane of the exterior casing H.

in the following specification and the claims the terms upper and lower will be used to 'de's ignate the storm window in its normal position of operation. The terms exterio'r, outward, outwardly and interior, inner or inward-1y all refer to a direction with respect to the build"- ing to which the storm window is applied when it is so applied in its normal position of use. The term eenterwardly wlll refer to a directionfro'm the edge or periphery of the storm window ward itsown geometric center.

Figure 1 of the drawings a storm window'as sembly; such as shown in my co=pending patent application Serial No. 681,245 on Storm window frame, filed July 3, 1946, is generally indicated by the numeral It and it will be observed that the extending surface flange thereof is indicated by the numeral It. It has been the previous practice to mount this extending surface flange M over the exterior surface of the casing" H. However, in the present invention the entire EtOlIm window assembly 13; including the flange M; is formed of an "over all size permitting to be positioned within the opening defined by casing H anew be mountedin flush relationship therewith.

In order to mount the storm window assembly l3 in flush relationship with the casing II, four sections of rolled metal shape are employed, two of which stand vertically at each side of the storm window assembly l3 and engage the extending surface flanges I4, and two of which are positioned in the upper and lower edges of the storm window assembly 13, respectively, and engage the extending surface flanges thereof. The rolled shape is indicated in the drawings in Figure 1 by the numeral l and comprises a shape defining a practically closed channel in that the surface flange thereof lies on the plane of the extended surface flange Id of the window assembly and on the same plane as the exterior of the casing H. The adjacent, or base, section of the rolled shape lies at right angles thereto, indicated by the numeral l6, and the third section lies at an angle with respect to the portion l5 and is indicated by the numeral [1, and the fourth section lies at still a different angle as indicated by the numeral I8. It will be observed that the fourth section l8 lies at approximately the same angle as the section l5 and that a very small opening remains between the free end of the section 1 8 and the inner surface of the section 15. The said sections H and I8 are sometimes hereinafter referred to as an L section. The narrow opening or slot in the continuously formed section, as shown in Figure 3, is suitable for the reception of the peripherially extending flange 14 of the storm window assembly [3. The rolled shape is so devised that when a screw I9 is positioned through appropriately located openings in the rolled metal shaped and driven into the blind stop [2, as shown in Figure 1, the net result is the distortion of the rolled metal shape bringing the surface flange section i5 thereof inwardly and bending the section I! to cause the section l8 to be brought forcefully against the inner surface of the extending surface flange Id of the storm window assembly i3. It will thus be seen that four sections of the rolled metal shape [5, when positioned around the surface flange Id of the storm window assembly l3, form locking and clamping means for mounting the storm window assembly 13in the dwelling house window opening. The locking action obtained between the outer end of the portion l8 and the inner surface of the fia'nge i 5 suitably positions the storm window assemblyv It will also be seen that it provides a relatively large tolerance in that it is operative with respect to any portion of the extending flange I l thereby enabling stock sizes of storm window assemblies to be employed in various sizes of window openings, the mounting means serving to compensate for the differences as well as the out.-0-f-square frames generally encountered. In Figure 2 of the drawings a similar construction is shown with the exception that a modification has been incorporated. The exterior casing is indicated by the numeral 2!], the storm window assembly by the numeral 2| and the blind stop by the numeral 22. The extending surface flange of the storm window assembly is indicated by the numeral 23 and the rolled metal shape is similar -to thatshown in Figure 1 and heretofore described with the exception that it includes, in

addition to the surface flange portion 24 and the clamping section 25, a filler section 25 formed as a continuation of the clamping section 25 and adapted to fill the space normally existing between the'outer edge of the blind stop 22 and the inner edge of the storm window assembly 2|.

The purpose of the modification is primarily to achieve an improved appearance from the interior of the window and it also has utility in that when a screw 2'! is tightened, the storm window assembly and the mounting member move inwardly toward the blind stop thereby bringing the clamping member 25 of the mounting member 24 into forceful engagement with the inner surface of the extending surface flange 23 of the storm window assembly 2!, and at the same time the space between the filler section 26 and the storm window assembly 2| is filled by the section 26. When the mounting member is sufficiently distorted, an additional clamping action is obtained by engagement between the filler section 26 and the storm window frame section 2|.

In Figure 3 of the drawings a perspective view of the clamping member is illustrated, the surface flange |5 thereof being shown in the lower portion thereof, the inwardly extending section being formed at right angles thereto, indicated by the numeral It as in Figure 1, the angular section indicated by the numeral I1, and the clamping section indicated by the numeral I8, all as shown in Figure 1. The screw I9 is shown in position in one of several openings formed in the clamping member.

In Figure 4 of the drawings a perspective view of the modified mounting metal section is illustrated, the surface flange 24 thereof lying at the bottom thereof and the filler strip portion thereof being indicated by the numeral 26 and the clamping member by the numeral 25. The screw 21 is also shown in one of the openings provided in the rolled section.

It will thus be seen that a simple and efficient mounting member for positioning a storm win dow assembly in a window opening and in flush relation to the casing has been disclosed, and

which mounting member differs from those heretofore employed in the art in that it avoids the usual U-shaped clamping arm construction and provides in its place a distortable member having a fulcrum point, as clearly shown in Figures 1 and 2 and indicated in Figure 1 by the numeral 28 and in Figure 2 by the numeral 29, by means of which fulcrum point the distortion of the member is accomplished when it is moved into engagement by the mounting screws l9 thereby causing the clamping member 18 to forcefully engage at right angles thereto the extending surface flange It of the storm window assembly I3, thus holding and locking the storm window assembly in a window opening and permitting the employment of small sized storm window frames in relatively larger openings by providing means for compensating for the difference and for filling the same'and, at the same time, providing an attractive as well as simple and inexpensive construction."

Having thus described my invention, what I claim is:

Framing construction for mounting a storm window, said storm window having a peripherally extending member, onto a window frame surrounding a window opening, the combination comprising: a blind stop on said window frame; a mounting frame having a base portion perpendicular to the outer surface of said blind stop and spaced therefrom, a flange extending centerwardly of said window opening from the window opening from the inner edge of said base portion, the leg of said L which is attached to said base portion forming an acute angle with the outer face of said blind stop and the apex of said L being against the outer face of said blind stop at a point thereon spaced center warclly of said window opening from said base portion, whereby the other leg of said L extends centerwardly and outwardly of said window opening toward the free edge of said flange; means defining openings through said flange and the said attached leg of the L-shaped portion, said openings being aligned on an axis substantially perpendicular to the outer face of said blind stop; progressively tightenable fastening means extending through said openings to the outer face of said blind stop for drawing said flange toward said blind stop; whereby upon drawing of said flange toward said blind stop, the said L-shaped portion will be urged to rotate on its said apex and urge its said other leg toward said flange.
